--------------NEW ITEMS-----------------

-------------Balance Changes------------

Big Bullet buff -> 20%-25% bullet size

>Hopefully this will make this item feel a bit better to take.

Lucky Nail nerf -> 1-0.95 worth

>This item as a first damage up is stronger than heavy burden and lemegeton. It is probably still a bit op because of a lack of downside.

The real downside to lucky nail is that it scales poorly

Mitosis Buff -> 0.65-0.7 worth

>The score loss was a bit too crippling.

Magazine Subscription Buff -> 1-1.05 worth

>This upgrade is on the edge of being good, but it scales with base clip size (which for the starter character is 6). 

It will be good in the future, despite how bad it is now.

Bullet Varnish Buff -> 0.06-0.09 lifespan

>A 50% lifetime buff will give this a more noticeable difference.

Sugary Concoction Buff -> 16%-20% movement speed, Now gives 10 max health

>This item is was just bad. Looking into other ways to make it stronger.

Heartbeat Nerf -> 1.2-1 worth

>For being possibly the best upgrade, it makes no sense to incentivize the player to take it.
